INSOLE FOR BOOTS AND SHOES.

Specification of Letters Patent.

Patented J une`11, 1918.

Application led April 30, 1917. Serial No. 165,360.

To all whom 'it may concern.'

Be itknown that we, EVERETT WV. FEs- SENDEN and HARVEY A. DUNN, citizens of the United States,- residing at Lynn, in the county of Essex and State of Massachusetts, have invented new and useful Im; provements in Insoles for Boots and Shoes, of which the following is a speciication.

This invention relates to an improved insole for boots and shoes,-the object of the invention being to provide an insole in which very thin, flimsy leather may be utilized and stillAthe insole be firm and strong for all practical uses to which it may be subjected.

The object of the invention is further to provide an insole of the character set forth which is made of two pieces of sheet material, one of leather and the other of canvas or other suitable textile material, which are joined together by stitches in such a manner that in the completed shoe the stitches do not show. 1

The invention consists in an insole constructed as hereinafter described and fully.

. the manufacture of a shoe.

Fig. 6 is a plan view ofthe completed insole.

Fig. 7. is a section of a shoe in process of manufacture with our improved insole incorporated therein.

Like numerals refer to like parts throughout the several views of the drawings.

Our improved insole is manufactured as follows: Two pieces of sheet material, preferably canvas and thin leather, are joined together by an adhesive material, such as cement and the soles are then dinked out of the sheet to form a sole such as that illustrated in Figs. 1 and 2, in which 10 is the textile material, such as canvas, and 11 is the leather.

The next step in the operation of manufacture of our improved insole consists in slitting the leather portion of the insole of stitches 15,v thus firmly uniting the canvas and the leather.

The next step in the operation is to lay the lip 13 back against the portion 14 of the part 11 and join the parts 13 and 14 by cement.

The next. step in the operation is to i turn the canvas up around its edge, from the shank portion around the toe portion of the sole to form a bead 16, this bead being turned up so that the inner side 17 of said lip is adjacent to and outside the row of stitches 15, as `illustrated yin Figs. 5 and 6.

The linnersole is then placed upon a last 18 the upper 19 of a shoe is lasted in the usual mannerand a welt 2O is attached to the upper and to the insole by stitches 21 which extend through said welt, upper and insole, as illustrated in Fig. 7. After the welt has been attached, the outsole is attached to vthe welt in the usual mannen and in the completed shoe it will be seen that the stitches 15 which join the two parts of the insole together will be hidden from view on the outside of the shoe; as said stitches terminate in the slit 12 -they will also be invisible from the inside of the shoe. Thus the inner surface of the insole of the shoe will be perfectly smooth and free from stitches, which is very desirable in the manufacture of a welt shoe, for if a row of stitches were to show on the inside of the insole of the shoe, it would give the same the appearance and have all the disadvantages of what is known as the McKay sewed shoe.

Having thus described our invention, what we claim and desire by Letters Patent to secure is:

l. An inner sole for boots and shoes hav ing, in combination, two thicknesses of sheet material, one ofsaid sheets of material only being turned up around its edge to form a lip, and stitches extending only through said last-named sheet material adjacent the inner side of said lip and only part way through said other sheet of material.

2. An inner sole for boots and shoes hav-v ing, in combination, a sheet of leather and a sheet of textile material, said sheet of texits edge to form a lip and stitches extending` only through said sheet of textile material adjacent the inner side of said lip and only part way through said sheet o leather.

3. An inner sole for boots and shoes having, in combination, two thicknesses of sheet material cemented together, one of said sheets of material only being turned up around its edge .to form a lip and stitches extending only through said last-named sheet of material adjacent the inner side of said lip and only part way through said other sheet of material.

4. An inner sole for boots and shoes having, in combination, two thicknesses of sheet material, one of said sheets of material only being turned up around its edge to form a lip, the other of said sheets of material being slitted around its edge and stitches extending only through said irst-named sheet of material adjacent the inner side of said lip, and only partly through Asaid last-named sheet of material and into said slit.

5. An inner sole for boots and shoes having, in combination, two thicknesses of sheet material, one of said sheets of material being turned up around its edge to form a lip, the other ot' said sheets of material being slitted around its edge and stitches extending through said rst-named sheet of material adjacent the inner side of said lip, eX- tending only partly through said last-named sheet of material and into said slit, the slitted portions of said second named sheet of l material being joined together with adhesive material.

` 6. An inner sole for boots and shoes having, in combination, two thicknesses of sheet material, one of said sheets of material being turned up around its edge to form a lip, the other of saidsheets of material being slitted around its edge and stitches extending through said first-named sheet of material adjacent the inner side of said lip and partly through said last-named sheet of material and into said slit, the slitted portions of said second named sheet of material being substantially parallel to each other.

7. An inner sole for boots and shoes having, in combination, two thicknesses of sheet i'uaterial, one of said sheets of material being turned up around its edge to form a lip, and stitches extending only through said last named sheet of material adjacent the inner side of said lip and only part way through said other sheet of material and in a direction approximately normal to the insole faces.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
